A DI box that can power your preamps Takamine CTP (watch for the CTP-1, you have to go through the upgrade of the original jack box which will increase the note)
Yes, it is relatively clear, but in English only.
Be careful, you will oblige to go through the transportation box for an additional box, a stereo jack and support for feeding the beast (power strip, extension cord ... because the power of origin you leave one meter of freedom).
Because of the power that the cable is too short, I put a 3 in use.
That does not sound worse than before when I used batteries.
I use it now for three years.
I repeat regularly in the studio and I have to carry more things then, add now becoming a real issue. The fact of not having to manage but battery power cables, additional jacks and a box of very heavy DI make me say that I certainly do not do it again this choice. In addition there happened to me an unfortunate history with the store that sold me and installed the DI + the famous jack upgradder my Takamine CTP-1: They ransacked my neck which had to be taken, refinished .. . remains and traces of their amateurism, and finally, they have to split half the box by screwing the new jack as nags (thank you shopping street of Douai ...). A guitar over 1600 € ...
Of course, I did break me question whether the batteries will hold out. But ultimately, if I could redo backtrack, I'll always have spare batteries with me and that's all.
